[jdk21u-dev] RFR: 8321025: Enable Neoverse N1 optimizations for Neoverse V2

[Xiaolong Peng]

### Notes
Backport 8321025: Enable Neoverse N1 optimizations for Neoverse V2  to jdk21 it is not a clean backport, the method ```model_is(0xd40) ``` is in jdk21, equivalent code in jdk21 is like ```(_model == 0xd40 || _model2 == 0xd40)```.

#### Verification
Not able to test it on CPU with Neoverse V2, since I don't have server supports Neoverse V2 yet, but the fix has been backported to [Amazon Corretto 21](https://github.com/corretto/corretto-21/blob/release-21.0.3.9.1/CHANGELOG.md
) since January 16, 2024, overall it should be a low risk.
